Can a member see the usernames of those they have referred?

[Infiniti Media]

As admin, I can see the usernames that a existing member has referred, but I've got members that want to be able to see the usernames of the people they referred. Is there a way to do this already?

I run monthly contests to see who can refer the most new members, so my members like to not only know how many they referred (which they can do by looking under statistics in their profile) but also the usernames of the new people they helped bring on board so they can send them a PM thanking them or welcoming them, etc.

Thanks in advance for any help on this!
